Abstract
In association with an imaging device which generates a portion of an image from a plurality of channels within a first row by sampling each channel during a sampling time corresponding to the channel, circuitry offsets sampling times of at least first and second channels within the first row, thereby reducing noise correlation between the first and second channels in the first row. Pixel sampling times may be defined by start times of the channels within a row, end times or both. Offsetting may be accomplished using a predetermined set of sampling time values or by randomizing sampling time values.
